The folks at RAD are awesome! They did the research and apparently All Balls stocks a set of bearing that will allow a 30 mm axle. A stock SE is 26mm and an adventure is 30mm. I have RAD making my spacers to spec. On another note the rear wheel from an SE is not a direct replacement. The only difference is the spacer on the disc side is narrower. I'm not sure what the SE has for a rear brake but my guess is its a different caliper/caliper bracket. Or the swing arm is just wider on the SE.

Here are my measurements and part numbers for bearings and seals to convert (Note: this is only for RAD hubs. The front is a single disc hub and rear is different from adv).

All Balls numbers:
Bearings x2: 20-1024
Seals x2: 30-5210

EDIT:
Front spacers:
RH: .292" no shoulder
LH: .635" no shoulder
Center spacer should be the same length just bigger ID to accommodate the 30mm axle.

Rear spacer (disc side)
.65" with no shoulder
Sprocket side is the same

So...$30 later and the bearings and seals are on their way Oh Joy!!! More great customer service from All Balls Racing.

Im used to people begrudging my attempts at customization. Some people are just too close minded. Its nice to deal with people that are willing to think a bit out of the box and help someone. RAD and All Balls are those kind of people. Defintiely will do business with them again.
